2 Claims.

A further object is to provide a mower utilizing laterally spaced rotarycutting elements adapted to be driven at high speed, means beingemployed whereby these elements can readily be adjusted upwardly anddownwardly while rotating.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings 7 Figure l is a plan view of [the mower attached to thefront end portion of a motor vehicle a portion of which is shown.

Figure 2 is a side elevation, the axle of the vehicle being shown insection.

Figure 3 is an enlarged section on line Figure 2.

Figure 4 is an enlarged view partly in elevation and partly in sectionshowing the spindle adjust ing means and adjacent parts.

Figure 5 is a vertical section through one of the belt pulleys and itsbearing.

Referring to the figures by characters of refer ence i designates aframe formed of channel beams or any other suitable material the frontend portions of which are connected by a platform 2 while the rear endportions are adapted to extend back to the chassis C of a tractor orother motor vehicle '1 which, as shown, is provided at one side with apower shaft S adapted to be driven by the motor of the vehicle by meanscommonly employed for that purpose.

Extending forwardly from the center of the platform is a tongue 3supported by a pilot wheel or caster l.

Secured to the platform 2 adjacent to one side thereof is a bearing 6and another bearing 0 is secured to the platform adjacent to theopposite side thereof. Bearing i is positioned adjacent to the forwardend of the platform while bearing 6 is positioned adjacent to the rearend thereof. 5 In these bearings are Journalled spindles l and I 8respectively and the upper portions of the spindles extend throughbrackets 9 mounted on and secured to the platform. Spindle I has apulley secured thereto between its bracket 8 and the 10 upper end ofbearing 5 while another pulley H is secured to spindle 8 between itsbracket 8 and bearing 6. The two spindles are adapted to slide in therespective pulleys but to rotate therewith.

A longitudinal shaft i2 is jourhalled on the 15 platform adjacent to oneside thereof and is so located that when this platform is properlypositioned in front of the vehicle T, shaft it will aline with the-shaftS, the two shafts being joined by a universal coupling indicatedgenerally at M.

A pulley it is secured to shaft l2 and is adapted to drive a belt itwhich engages the two pulleys it and ii and also engages an idler pulleyit located between platform 2 and a bracket ll. Thus it will be notedthat when shaft tits rotated, motion will be transmitted therefromthrough the belt to the two spindles i and d which will berotated in thesame direction at a high speed.

Each of the spindles i and t is provided with 353 a collar it! and anadjusting lever id embraces each spindle below the collar. This lever isfulcrumed at one end on a bracket it as shown for example in Figure 4while its other end carries a spring-pressed'dog 2i adapted to engageany $5 one of a series of notches it formed within a bar 2i. Obviouslyby means of lever it its spindle i or it can be lifted and supported ata desired elevation without, however, interfering with its rotation. Byreleasing dog 22, the spindle can so be lowered to a desired point.

These spindles are preferably supported by tapered anti-friction bearingelements as indicated generally at it. Oil cups 2% can be locatedwherever found desirable.

To the lower end of each of the spindles l and d is secured a sleeve it,the same being held thereto by a set screw it or the like. Each sleeveextends upwardly from the center of a flange it which, in turn, isbolted as at 29 to a disk 30. 6| Cutting teeth 3! are fastened to themarginal portion of the disk 30 and extend radially therebeyond and thetwo disks are so located with respect to each other that the swaths cutby the two disks will come together or slightly lap 55 thereby insuringan unbroken cut the width of which is substantially equal to thecombined maximum diameters of the two cutting elements. As the two disksrotate simultaneously in a counter-clockwise direction as viewed inFigure l, the grass or other vegetation cut by the front -disk will bethrown thereby from the left side of the machine and the vegetation cutby the other disk will be thrown to the left and back of the front disk.Thus there is no danger of the cut material being thrown into the pathof the vegetation in the path thereof and clear said' path.

What is claimed is:

1. A mowing attachment for motor driven vehicles including a platform, asupporting wheel at the front end thereof, means for attaching the rearend of the platform to the front of a motor vehicle, front and backupwardly extending spindles mounted for rotation in the platform, saidaae ses direction thereby to operate the front cutter to throw outmaterial laterally beyond one side of the machine and the rear cutter tothrow cut 10 material laterally into position back of the front cutter,and means for coupling said shaft to a drive shaft on the vehicle.

4 2. A mowing apparatus including a platform for attachment to the frontend of a vehicle, supporting wheels for the platform, front and backvertical spindles positioned adJacent to the respective sides of theplatform and mounted for rotation in the platform, front and backcutters connected to and rotatable with the respective spindles, andmeans for simultaneously rotating the spindles and cutters in onedirection, the front cutter constituting means for throwing out materiallaterally beyond one side of the platform and the rear cutterconstituting means for throwing cut material laterally into positionback of the front cutter, said cutters being positioned relative to eachother to cut meeting swaths extending throughout the width of theplatform.
